Extraterrestrial life is defined as life that does not originate from Earth. Life on other planets is a simpler way to word it. Aliens on other planets is an example (but I doubt aliens live on other planets) of extraterrestrial life. Also, bacteria are another example. There is proof that there was once water on Mars, and that there may have been bacteria living in that water. That bacteria would also be considered as extraterrestrial.
